SPECIFICATION forming part of Letters Patent No. 619,082, dated February'7, 1899.

Application filed September 428, 1898.` Serial No. 692 J066. (No model.)

To all wiz/0m it may concern:

Be it known that we, JAMES MALLON and OvID CREPEAU, citizens of theUnited States, residing at South Bend, in the county of St. Joseph andState of Indiana, have invented certain new and useful Improvements inSand- Bands; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as Will enable othersskilled in the art to which it appertains to make and use the same.

Ou-r invention relates to improvements in devices for excluding dust orsandfrom the spindle of a vehicle-axle and for preventing thelubricating-oil from escaping from the spindle onto the adjacent partsof the axle and Wheel-hub, said devices being commonly designated assand-bands or spindle-protectors.

The objects of our improvements are to provide a device of thischaracter which can be cheaply made, readily applied to all the ordinaryforms of Wagon-skeins, and which Will be thoroughly effective as a dustand sand excluder.

Further objects are to provide means by which the device may be adjusted as the parts wear and whereby the removal of the Wheel for thepurpose of oiling the spindle will not be interfered with by thesand-band and the latter will not come away with the Wheel.

The manner in which we obtain the objects above set forth will behereinafter described tion in a preferred form is illustrated in theaccompanying drawings, which form a partV of this application, and inWhich- Figure l is a sectional view of a portion of a Wheel-hub andaxle-box with our improved sand-band applied, said band being shown invertical section and the axle-skein in side elevation. Fig. 2 is a frontelevation of our improved sand-band, and Fig. 3 is a vertical section ofthe band on line a: :c of Fig. 2.

Like reference-numerals indicate like parts in the several views.

Referring to the drawings, l represents an axle-skein of common formhaving the usual shank la and dust-collar 2. 2 represents sufiicient ofa wheel-hub to illustrate the application of our invention. Said hub isprovided with a central longitudinal bore for the reception of theskein-box 2C, into which fits the spindle l, all of well-known form andarrangement. In the face of the inner end of the hub 2 is a horizontalannular groove or recess 2b of sufficient depth and width to receive theflange 3d of the sand-band 3. This sand-band consists of an annularmetallic ring, which is split or divided at the point 4 and is formedwith a plurality of lugs Which extend from the periphery of the bandopposite the flange 3 and curve inwardly and downwardly. On the ends ofthe band are lugs 3b, which are perforated for the reception of a smalltie-bolt 4?, having a suitable nut, by means of which the sand-band istightened and securely held on the dust-collar 2, the

latter being embraced by the lugs 3f. On the inner periphery of thesand-band is an annular shoulder 3, which when the band is in positionfits closely against the dust-collar, thus preventing the admission ofdust to the spindle and also serving, with the lugs 3, to hold thesand-band on the skein.

It will be apparent that various modifications, may be made in the formof our improved sand-band Without altering the scope of our invention.The groove or recess 2" may have slightly-curved instead of straightWalls, the number of lugs may be increased, and the band may be formedof ductile material Without the necessity of dividing it, as the lugs 3ucould be bent down over the dustcollar 2a. The sand-band iiange 3d couldbe made Wide enough to provide for considerable lateral play of theWheel. It is also apparent that as the portion of the hub between.

the sand-band and the axle-box becomes Worn a close joint may at alltimes be maintained. It will be noted that the annoyance of having thesand-band drop off when the wheel is removed (a fault common to all ofthe ordinary sand-bands) is entirely prevented by the grip on thedust-collar, which is maintained in our invention by the lugs.

Having thus described our invention, what we claim as new, and desire toobtain by Letters Patent, is-

1. In combination With an axle-skein hav- IOO ing a dust-collar and ahub having an annular groove of a sand-band having a flange adapted toenter the groove of the hub, and

. with lugs adapted to embrace the dust-collar der and inwardly anddownwardly extending lugs, substantially as set forth.

4. A sand-band composed of a divided ring having an annular flange, anannular` shoulder,inwar'dly and downwardly extending lugs, and lneansfor Connecting the ends of `the band, substantially in the manner andfor the purpose set forth.

In testimony whereof we affix our signa- .25

tures in presence of two witnesses.
